Multi-factor authentication (MFA)

Multi-factor authentication (MFA) requires two or more independent factors — something you know, have or are — to sign in, of which 2FA is the common two-factor form.

Definition

MFA combines factors from different categories: knowledge (password), possession (a code or passkey on your device) and inherence (biometrics). Requiring more than one makes a single stolen credential useless.

Why it matters for your business

For business accounts, enabling MFA is the strongest routine defence. On a Credit Corp account this means a password plus an authenticator code or a passkey — see setting up 2FA.
